When I finish a turn against my opponent and click end game the wheel pops up and keeps spinning and the game doesn't shut down. I think the turn gets through, I will have to check. I am playing a pbem game with my opponent.

If you're reading this and you're not sure whether you have version 1.01, you can go to "Credits" from the main menu: at the bottom of credits it should say "version 1.01" otherwise it's 1.00 and you need to patch up.
